I wish to purchase a smartphone-compatible microscope, primarily for counting scales on small lizards, identifying invertebrates etc. A low magnification capability (e.g. 5 or 10x) is more important than high. A lot of the devices I've seen online start at (e.g.) 50x zoom, which is generally too much magnification for my needs. My ideal would be something that can be attached to a stand, has built-in LED, and if possible also doubles as a borescope (to investigate tree hollows, burrows etc.). I plan to use it for field work, hence the desire for a multi-purpose device. Please can anyone suggest something suitable?
